I hope Apple follows its own rules. Remove arcade from the App Store, make it its own app, and bring the updates tab back.
Then, if you have the arcade app on your phone, you can use it to link to every single game. Every game will have its own App Store page, so when you tap an app from the arcade user interface, it will open an App Store page where you can download it.
